CORN AND r'o'm'ro PLANTER.

Patented Jan. 21, 1908.-

Application filed May 4. 1907. Serial No. 371.898.

- My invention relates to an improvement in corn and potato planters, and is designed more particularly as an improvement 'on the construction disclosed in myPa-tent No. 760,872, granted to me May 24, 1904, and it gconsists in the parts and combinations of parts and in the details of construction as will he more fully described and pointed out in the claims.

. In the accompanying drawings, Figure 1 is arview inside elevation of I y improvement. Fig. 2 is a plan view of same. Fig. 3 is a View in rear elevation of the auxiliary disks "and Fig. {l is a view in elevation of one of the In my Patent 760,872 the convex furrow opening disks are journaled in bars which are secured to the underside of channel irons extending from side to side of the'inachine and constituting a part of a frame carried by the tongue of the planter, the rearend of this frame being pivotally connected with a frame or truck mounted on ground or covering wheels. These bars which carrythe concavo-convex furrow opening disks, are located to the outside of the disks, the latter resting within the space formed by the divergent arms.

In this invention 1 support the main concavo-convex furrow opening disks 1 by a malleable castin 2 depending from the channel irons 3 whic bear the same relations to the planter as the channel irons of the patented planter above referred to. Each casting 2, one on each side of the planter, is approximately V-shaped in side elevation and is provided adjacent to its lower end with a bearin 4 the side faces of which converge forwardly at acute angles to the side of the casting 2 so as to permit the disks to be placed at their proper working angles and well up to the castin or frame 2. The bearing l is provided wit an angular opening for the reception of the axle 5 the central portion of which is angular in elevation and also in cross section, while its spindles arcf" I drical and project forwardly 'ando' itwarcljg from the central portion of the axle andrej ceive and support the (lislsf. 1"whiclr latter operate to open the furrow in advanceo'f the seed dropping boot or tube 7 The disks 1 are fixed inposition as'to lateral spac-i'ng by the cup shaped washers 5 which bear at one end against the shoulders on theaxle, and at their outer ends against the disks. T he concave side of these washers overlap and cover the ad acent" side of bearing or hubTof the disk and protect the same from the dirt;

These washers hold the axle in a central po sition in casting 2, and are lockedagainst rotation and longitudinal movement on the axle, by the cotter pins 7. The disks 1 are held in'placeon theaxle by cup shaped washers 8 and pins 0;-

Projecting rearwardly from the casting or frame 2 is the arm 9, having the socket 10 through which the seed tube 7 passes, the seed. tube being preferably angular in crosssection as shown in Fig. 2. so asto prevent it from turning, and is held in place and vertically adjusted by the setscrew ll. r a' Projecting forwardlf from the front face of the seed tube is the bearing 12 having an arr gular opening throughsan'ie for the passage of the axle 13 carrying the auxilia ydi's'ks 14-, the axle being sul'istantially of the same construotion as the main axle, and the disks i'lat instead of concave-convex. The disks-are secured to the axle by means similar to those employed, for holding the main disks in place, and may be separated or brought closer together by means of cup shaped Washers, of varying thicknesses. These auxiliary disks are smaller than the main disks and follow in the furrow of main disks and operate to open up and deepen the furrow immediately in advance of the exit end of the tube 7 ,so that the loose earth as it falls back into the furrow in rear ofzthe auxiliary d sks will cover the seed, the covering or burying of the seed be ing assisted by concave I'llllllled ground wheels similar to those shown. n my patent above referred to.

Pivotally mounted on a lug 14 on the rear face of tube 7 are the scrapers 15 which latter are yieldingly held in contact with the plane faces of the disks by the spring 16 mounted on the rod 17, one end of the latter being secured to one scraper, with its opposite end passing through a hole in the ot 161' scraper.

By this arrangement the scrapers bear with a yielding pressure sufficient to dislodge andclear the disks of any adhering dirt.

Secured to the front of the frame or castingj2, near-the lower end of the latter is the draftrod 18, which latter is attached at its. "front end to the frame of the machine, and

connecting the frame or casting 2 and seed tube 7 near the lower end of the latter is the draft 'rod 19, the latter being pivotally secured .at its ends so as to'permit of vertical adjustment of the 'seedtube. I

It is evident that changes in the construction andjrelative arrangement of the several parts might be made without avoiding my invention-and hence L'would have it understood that I donot restrict myself to the par.

ticular construction and arrangement of parts shown and described, but,

Having fully described my invention what I claim as new and desire to-secure-by Letters'-Patent,is: I

1., In aplanter combination with a main frame and a def ndiiigframe, the 1alof the depending frame, a seed tube-connect-.

ter rovided with a":rearwardly projecting 'arm avin a socketedv ortionat its free end,

of a 'seed tube vertica y adjustable through said socketed portion, a, brace connecting said-seed tube with the lower portion of the depending frame, and disks mounted at the lower ortion of said depending frame.

-2. n a planter, the combination with a main frame and a frame depending therefrom, of an axle carried by the depending' frame, disks on said axle at respective, sides ed with the upper portion of the depending frame, aconnectioncbetween the lower portion of saidseed tube and the lower portion of the depending frame, and means carried by the lower portion of the seed'tube for cutting the furrow 3. In a planter, the combination of a pair of main disks, a pair of auxiliary disk's inrear frame, a seed-tube in rear of the main disks,- connections between the upper and lower frame and the seed portions of the dependin tube, and auxiliary disks mounted on the seed tube and following in the furrow of the main disksti" 5. In a planter, the combination of two. main disks, a seed tube in rear of the maindisk's, auxiliary disks. mounted on the'seed tube and following in the furrow of the main disks, and yielding scrapers also carried by said tube and bearing against the faces of the auxiliary disks.

adjacent,

6. The combination with'a depending frame, an axle having an angular central portion and cylindrical ends mountedin said.

frame, the spindles of said axle rojectin outwardly and forwardly from t e centrfi angular portion, main disks on said spindles, a seed tube in rear of the disks and carrying auxiliary disks mounted on an axle similar to the axle of the main disks, and a brace connecting the depending frame and seed tuba,

In testimony whereof, I have signed this specification in the presence of two'subscribing witnesses. IRA JAMES KAAR.
